How many solutions does this system have?

Answer:

The correct option is d.

Step-by-step explanation:

The given equations are

x-2y=2                 .... (1)

y=-2x+5               .... (2)

In equation 2, multiply both sides by 2.

2y=-4x+10               .... (3)

Now add equation (1) and (3).

x-2y+2y=2+(-4x+10)

x=2-4x+10

x+4x=12

5x=12

Divide both sides by 5.

x=\frac{12}{5}=2.4

Put this value in equation (2).

y=-2(2.4)+5

y=-4.8+5

y=0.2

Therefore the solution of the system of equation is (2.4,0.2) and the system has only one solution. Option d is correct.

Answer:

R(x,y) = (0.8,-1.2)

Step-by-step explanation:

The coordinates of QS are:

Q(x_1,y_1) = (-2,-6)

S(x_2,y_2) = (5,6)

The ratio is represented as:

R_{m:n} = 2:3

Required

Find the coordinates of R

The coordinates of R is calculated by:

R(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

Substitute values for m, n, x's and y's

R(x,y) = (\frac{2 * 5 + 3 * -2}{2+3},\frac{2*6 + 3*-6}{2+3})

R(x,y) = (\frac{4}{5},\frac{-6}{5})

R(x,y) = (0.8,-1.2)

<em>None of the options is correct</em>

Its DBC, cause two is in that point so you just find the answer choice with those three letters in the right order.

2 angles measure 40 degrees each, what does the third angle measure? what type of triangle is it?
zimovet [89]

Answer:

Part a): 100 degrees

Part b): Isosceles Triangle

Step-by-step explanation:

Part a): Since the angle measures of all triangles add up to 180 degrees and since the other two angles are 40 degrees, which add up to 80, we can use subtraction to find the answer.

180 - 80 = 100

Part b): Since only two of the three angles in this triangle have the same measure, we can find that it is an isosceles triangle, with base angles measuring 40 degrees, and the vertex angle being 100 degrees.
